Introduction
GDVA-405 Automatic CT PT Analyzer is suitable for testing all kinds of current transformer and voltage transformer,also called CT and PT.
GDVA-405 CT PT Analyzer can calculate the ratio errors and phase angle errors of CT and PT at rated burden and working burden in one time.
It can also automatically evaluate the test results according to the selected standard(IEC60044-1,IEC60044-6,IEC61869,IEC60044-2,IEC60044-5,IEEE Std C57.13-2016) to determine whether the transformer is qualified. And give an indication of ”Pass” or ” Fail”.
Advantages for GDVA-405 Automatic CT PT Analyzer
The accuracy is 0.02%(typical), 0.1% (guaranteed).
Three or more consecutive measurements of the same sample CT, the repeatability within 0.02%.
Can test all types of CT: M, P, TPY, Bushing CT, GIS CT.etc
Comply with a variety of international standards: IEC60044-1, IEC60044-6, IEC61869,IEC60044-2, IEC60044-5, IEEE Std C57.13-2016.
All the test items can be completed in one time.
Ultra-high measurement accuracy and strong data management capabilities.
The max knee point voltage of GDVA-405 CT PT Analyzer is 60kV.
Excellent workplace safety - Tests run at max.180V.
Short commissioning times (duration of the automatic test < 1min)
Calculate the ratio errors and phase angle errors at rated burden and working burden in one time test
Compare excitation curves with saved excitation curves in the same window
Embedded computer, powerful application software support.
Ultra-wide measurement range.
Replace traditional CT calibrator.
